PUMP-CYLINDER.

SPECIFICATION forming part of Letters Patent No. 763,028, dated June 21,1904. y Application filed September 19, 1902. Serial No. 124,068. (Nomodel.)

To (LN, whom it may concern:

Be it known that I, RUDOLPH STONE, acitizen of the United States,residing' at Catawba, in the county of Price and State of Wisconsin,have invented.v a new and useful Pump-Cylinder, ofI which the followingis a specification.

This invention relates to the cylinders of pumps and similar structures,and has for its `Object the production of detachable ends for thecylinder which may be readily attached to and detached from the cylinderand rotatively adjusted thereon independently of the cylinder and of theplunger or piston-head.

To thisend the invention consists in the details of construction, ashereinaftershown and described, and specified inthe claims.

In the drawings illustrative of the invention, Figure 1 is a sideelevation, partially in section, of a pump-cylinder embodying theimprovements; and Fig. 2 is a` plan view of various forms ofpump-cylinders and may be applied to some forms of' steam-engines andsimilar structures, and I do not, therefore,

wish to be limited in any manner to the form of structure to which theinvention lmay be applied. i

The improved device is more particularly applicable to pumps and othersimilar structures which are exposed to moisture, whereby rust gathersaround the holding-bolts and renders the detachment of the parts amatter of extreme difficulty.

For the purpose of illustration the invention is shown applied toapump-cylinder (indicated at 10) and provided with a plunger 11 andpump-rod 12 of the usual construction. The cylinder 1() is provided-atone or both ends with laterally-extended flanges 13 of comparativelygreater length longitudinally of the cylinder than ordinary flanges,asshown. As the structure of both cylinder ends is substantially the same,like designating characters are employed to denote corresponding partsin each. The ends of the cylinder are indicated at 14 and are eachprovided with a depending peripheral flange or rim 15, closely engagingand rotative upon the periphery of the flange 13, the length of thedepending flange or rim corresponding to the length of the' flange, asshown, so that a comparatively extensive contact area is providedbetween the cylinder i and cylinder ends. nall y disposed in thedepending rims or flanges 15 at suitable interval-s are bolt-apertures16, the apertures being continued through the cylinder en ds,as shown.Any required numberof th'ese'apertures may be employed, according to thesize of the cylinder; but for the purpose of illustration four are shownspaced apart and opening .inwardly against the flanges 13. Theholding-bolts are indicated at 17, passed between the flanges l13 and 15and provided with laterally-extended heads 18 upon their inner ends,adapted to project into engagement with the outer surface of the flanges13, as shown, and with nuts 19 upon their outer ends. By this simplearrangement it will be obvious the cover memberslll will be firmlysecured in place upon the cylinder by the coaction of thelaterally-extended heads 180i' the bolts and the flanges 13, while atthe same time leaving the end members free to be rotatively adjustedupon the cylinder, as the heads 18 of the bolts will engage 'the loweredges of the flanges at all points of the circumference of the anges. Bythis means the end members may be rotatively adjusted upon the cylinderindependently of the cylinder, pump-rod or plunger, which is a verydesirable advantage under certain circumstances.

If the end members and their bolts after long exposure to moisturebecome rusted fast,

Longitudithey may be readily loosened by slightly reversing the nuts andapplying a rotative force to the cover member to break it loose,l.whichaction will not inA any manner `inj uriously affect the pump-rod orplunger or other parts, as will be obvious. By this peculiar and IOOwhich action leaves the ends free to be moved longitudinally orrotatively, as may be found most convenient in loosening them previousto their removal. By this simple construction a cylinder end is producedwhich may be very readily connected to and disconnected from thecylinder and adjusted to any required extent and which will never becomerusted fast to the cylinder to an extent suflicient to annoy theoperator in his'eforts to remove them.

The device may be applied to pump-cylinders'of any size or capacity orto other similar structures. n

It will be noted that by this invention the cylinder ends may beconnected to the cylinder at any point in their circumference and noattention need be paid to the relative rotative position of the parts,as the heads 18 of the bolts [it the flanges 13 at one point as well asanother.

Another advantage to be noted is that the mechanism of the pump abovethe cylinder may be turned to any desired point independently of thecylinder or the cylinder adjusted rotatively to any desired extentindependently of the` mechanism above the cylinder, which will on manyoccasions be a very desirable and useful advantage, especially when thepump or other structure and its operating mechanism are located incramped quarters, as frequently occurs.

Another important advantage of the improved device is that thecomparatively long bearing-surfaces between the end members and thecylinder irmly support the parts, so that lateral strains are borneentirely by the cylinder and the depending portions 15 of the ends andthe bolts relieved from lateral strains.

The intake-pipe is indicated at 2O and the discharge-pipe fitting at 21,of the usual form; but it will be understood that the device may vbeemployed in connection with any form of cylinder-pump or similarstructure, and I do not wish to be limited in any manner in theemployment of the improved device with any specic arrangement of theintake or outlet piping'or their connections.

ing a cylinder provided at each end with a laterally extending iange,cover members each having sides adapted to engage the periphery of theflange at one end and terminating flush with the lower surface of saidange, and separate securing means for said cover members, said securingmeans comprising bolts provided with squared heads arranged in suitableapertures in said cover members and having the heads engaging theflanges on the cylinder and contacting With the outer surface of thecylinder to prevent rotation of the bolts.

2. A device of the class described comprising a cylinder provided ateach end with a laterally-extending flange, cover members for the endsof said cylinder each having sides adapted to engage the periphery ofthe flange at one end of the lcylinder and terminating flush with themargin of the iange remote from the end of the cylinder, and independentmeans for securing said cover members so thatthey may be independentlyrotated on said cylinder or removed therefrom, said means comprisingbolts with square heads arranged in suitable apertures in said covermembers and having the heads engaging the anges on the cylinder andlying in contact with the outer surface of the cylinder.

In testimony that I claim the foregoing as my own I have hereto aiixedmy signature in the presence of two witnesses.
